To withdraw HMDX from BNB Smart Chain to Ethereum (ERC20), it needs to be first bridged back to HECO. 2.Contract address for MDX (ERC20): 0xc56725b6430132DE775C4e5B48c9B0318CE2fC69 MDEX team June 16th, 2023 --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://mdexdoc.gitbook.io/doc/announcement/announcement-on-mdex.com-has-officially-launched-the-cross-chain-bridge-functionality.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
